GAS-RADIATOR.

Application led April 2, 1918, Serial No. 226,143.

To @ZZ 'u1/tom it may concern.' l

Be it known that I, IinGnNDnn CINQ-Minis, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Gas-Itadiators, of wh'ch the following is a specification.

rlhe present invention relates to that class of gas radiators in which the gas burner and combustion chamber are centrally located and the products of combustion pass outwardly through the tops of side members and inwardly through the bottoms of said side members.

One object of the invention is to provide a gas radiator so constructed that, when the gas is first ignited, the flame cannot be eX- tinguished by the pressure of the' column of cold air in the stack, or other back pressure it a stack be not used.

.i further object is to provide, in use with such a radiator, means whereby a back draft in the stack or other back draft will escape into the room without aiiecting the combustion at the burner.

A. further object is to provide, in use with such aradiator, means whereby a back draft in the stack or other back draft will promote a circulation oi the heated products of combustion through the radiator in the proper direction.

A further object is to provide, in such a radiator, an outlet into the room which will permit the escape of the air in the radiator, when it cannot otherwise escape, as, on account of the pressure of the column of cold air in the stack the escape of air thus permitting the products of combustion to pass freely through the radiator.

further object is to provide, in such a radiator, means for quickly expelling said column of cold air, or for heating the same to such a temperature as to produce the normal draft in the stack.

further object is to provide means for preventing the stack temperature becoming unduly high, with attendant loss of heat.

@ther advantages will appear from the description of the invention hereinafter set forth, and will be particularly pointed out in the claims.

In the accompanying drawing, Figure 1 is a front view of my improved gas radiator; Fig. 2 is a vertical central transverse section thereof on a larger scale; Figs. 3, 4, 5, are

.municating with each other at the top and bottom in the usual manner.

The products of combustion flow from the bottoms of the side members 3 into a conduit S within the lower portion of the centrai member 2, said conduit leading out at the back of the bottom of said central member, and then upwardly, and communicating at the top with the mouth of a tapering guide 9, and thence to the stack 1l.

In the lower part oi the central member 2 is a gas burner 12, having a central air passage, and supported by a gas pipe 13 screwed thereinto, extending through an air opening 14 in the bottom lower end oi the central chamber, and connected through a valve 16 with a source of supply of gas. Secured to bosses 174 formed on the inner surfaces oi the sides of said central member are angular plates 18, on which are supported the four corners of a hood or shield 19, which also serves as a detlector, preventing tlie flames of the burner from being extinguished by the products oi' combustion descending thereon in the central chamber when the burner is first ignited and said products are not able to flow by their normal path through the side members 3 and up the stack.

Said products oi combustion are deflected by said hood or deiicctor 19 and caused to pass partly through holes 21 in the side of the central member and thence into the room which is being heated, and partly through an elongated hole 22 in a wall 23 of an air-heating conduit 24 located within the rear lower portion of the central member, said products thus passing by said conduit 24, either by a horizontal conduit 26 communicating with said tapering guide 9, or, if the pressure in the stack be too great, downwardly by a hole 27 at the bottom of said conduit 24 into the room. In this way, when the gas is first ignited, and the pressure of the cold air in the stack is too great to permit the products of combustion to iow in their normal manner through the side members and thence into the stack, said product-s of combustion will not extinguish the iames but will escape into the room until such time as the temperature in the stack becomes sufficiently high to permit the products of combustion to flow thereinto.

The holes 2l admit secondary an for combustion to pass into the combustion chamber over the hood 19, while said hood prevents the flames from passing directly out through said holes 2l.

Should the products of combustion be able to flow in their normal path outwardly through the tops of the side radiating mem- `hers 3 and inwardly through the bottom of said members, but not be able to overcome the pressure of the cold air in the stack, they would flow upwardly by the conduit and thence by the conduits 26, 2li, and out of the room by the hole 2T.

Very soon after the gas is ignited, however, the air in the conduit is suil'iciently heated to start moving upwardly the column of cold air in the stack. The continued upward motion in the stack and the motion of the air into the mouth of the converging guide 9 produces a suction in the supper portion ot' the conduit 24, and causes vvelocity when leaving the guide, and thus by forming a jet across the conduit S creates an upward suction in said conduit and into the conduit 26, then down through the conduit 2a into the room, and thus promotes normal circulation in the radiator.

The conduit 24 is of advantage when the burner has been well started and the products of combustion are flowing in their norma] paths outwardly through the tops of the side radiating members and inwardly through their bottoms and thence by the conduit 8 and up through the stack, as it causes a certain amount of comparatively cold air to be drawn up through the air conduit 24, which mingles with the products of combustion in the stack and reduces the temperature ol the stack.

ln addition, this construction is of ad vantage since this current of air in the conduit 24 draws otl' the impure air in the botlem of the compartment through the hole 2T.

l claim l. gas radiator having a central member, side radiating members communicating at the top with'the central member, a discharge conduit leading outside of the central member and communicating with the bottoms of the side radiating members, an airheating conduit communicating with the atmosphere and with the discharge conduit, and a converging guide located in said discharge conduit opposite to its uncture with said air conduit.

2. A gas radiator, having a central member, side radiating members communicating at the top with the central member, a discharge conduit communicating with the bottoms of the side radiating members, and leading outside of the central member, first, upwardly and then changing its direction, and an air heating conduit communicating at a lower point with the atmosphere and at an upper point with the part of the discharge conduit at which it changes its d1- rection.
